核电PTR储罐下封头带垫板对接焊缝射线检测底片的黑线影像
Radiographic testing films black lines on butt welding with backing plate on the nuclear power PTR storage tank bottom head
摘 要
对核电站反应堆换料水池和乏燃料水池冷却和处理系统（PTR储罐）下封头射线检测底片出现的两种黑线影像进行研究，结合底片影像特点对工件进行解剖验证，分析了黑线产生的原因及其特点，为后续带垫板对接焊缝射线检测底片的评定提供了参考。

Abstract
The two black line images appearing in the radiographic detection film of the lower head of the nuclear power plant reactor refueling pool and spent fuel pool cooling and processing system (PTR storage tank) were studied, and the workpiece was anatomically verified based on the characteristics of the film image, and the black line was analyzed. The cause and characteristics of the line production may provide a reference for the subsequent evaluation of the radiographic inspection film of the butt weld with a backing plate.
